WHAT HAS CHANGED

Freeze Warnings and Frost Advisories have been issued for the Hudson Valley, southern Taconics and Litchfield County, CT for tonight.

KEY MESSAGES

1) Cold temperatures tonight will lead to areas of frost across all of eastern New York and western New England, including areas with the growing season ongoing.

2) Temperatures moderate back to near normal values for the mid to late week with chances for light rain showers for northern and western areas at times.

DISCUSSION

KEY MESSAGE 1...

High pressure will continue to build into the area today and be directly overhead tonight. Mostly sunny, breezy and dry weather is expected today, though winds will not be as strong as on Monday (gusts mainly 15 to 25 mph). Temperatures will run 5 to 10 degrees below normal today with values ranging from the upper 40s across the Adirondacks and southern Greens to the lower 60s across the mid-Hudson Valley. A continued mostly clear sky combined with light to calm winds will allow for ideal radiational cooling conditions tonight with temperatures falling rapidly at sunset. Some patchy high clouds may pass through across areas north of I-90 overnight but should do little to prevent cooling temperatures. Most valley areas will likely fall into the low to mid-30s with some mid to upper 20s across the Adirondacks and southern Vermont. This will allow for frost to form across most of eastern New York and western New England, including the Hudson Valley, southern Taconics and Litchfield County, CT, where the growing season is ongoing. Freeze Warnings and Frost Advisories have been issued for these areas for tonight as confidence in these temperatures have increased.

KEY MESSAGE 2...

High pressure shifts to the east by Wednesday allowing for south to southwesterly return flow to resume. This will allow for more seasonable temperatures to return and continue through next weekend. Longwave troughing sets up across the region later this week as a series of weak disturbances track near the U.S./Canada border. This will allow for some light rain showers at times mainly for northern and western areas. Surface high pressure and upper ridging builds in for next weekend with dry weather regionwide.

AVIATION /06Z TUESDAY THROUGH SATURDAY/

Through 06z/Wed...VFR conditions are expected through the upcoming TAF period. Patchy low to mid-level clouds at KGFL/KALB/KPSF for the remainder of the overnight will give way to nearly SKC conditions today into this evening with just a few passing high clouds at times. West to northwesterly winds 5-12 kt through the overnight will increase to 10-15 kt on Tuesday with gusts around 20 kt. Winds trend light to calm tonight.

Outlook...

Wednesday Night through Sunday: No Operational Impact. NO SIG WX.
